Re: Placeholders in NCL Script?

Hi Cory,

For future reference: it's better to post NCL questions to ncl-talk rather than ncarg-talk.

If I understand your question correctly, you should be able to do this using command line options.

For example, the beginning of your script might look something like this:

  needed_vars = (/"Y","M","D","H","m","s"/)

  if(.not.all(isvar(needed_vars))) then
    print("Error: one or more required variables have not been input.")
    exit
  end if

  MM = sprinti("%02d",M)
  DD = sprinti("%02d",D)
  HH = sprinti("%02d",H)
  mm = sprinti("%02d",m)
  ss = sprinti("%02d",s)
  filename = "wrfout_d01_" + Y + "-" + MM + "-" + DD + "_" + H + ":" + mm + ":" + ss

  print("filename = '" + filename + "'")

and then you can pass in the six needed variables on the UNIX command line with:

ncl Y=2010 M=2 D=5 H=20 m=3 s=20 test.ncl

Is there a way to use a placeholder for dates/times in the filename inside NCL so that cron will be able to run the NCL script without intervention? Something such as wrfout_d01_YYYY-MM-DD_HH:MM:SS ?
